The area of a rectangle is given by the expression x2 + 5x + 4. If the length of one side is given by x + 2, what is the length of the other side?

Thank you for the opportunity to help you with your question!

x2 + 5x + 4.

x + 2

Area=length×width

X^2+5x+4=x+2 (w)

Divide through by x+2

Factor out the area equation

Ans= (x+4) (x+1)/(x+2)
